Lew,
I only will use the RoadRunner for a readout in place of the strobe light, I will of curse leave the original control system in place.
You mention that the RoarRunner only looks at the RPM once a revolution and while this is correct if there was any deviation what so ever it would not read out 33.333 which is typically does on these fine machines. The Strobe light on the DP80 is hard to retrofit into the plinths as the platter is fairly thick which requires the mirror be sunk deeper into the plinth for sufficient readability.
In rebuilding the DN308 tables which does not have a strobe i wanted a way of displaying the RPM and the Roadrunner its easily customized into the plinth, which in case of the DN308 will be a 1" thick Aluminum plate top and bottom sandwiching a hardwood frame. This lead to wanting to do a "professional" version of the DP80. Below a little sneak peak :-)
